The SiAW is an air-to-ground weapon developed to strike relocatable targets within an anti-access/area denial (A2/AD) environment. It leverages digital engineering and open systems architecture to provide rapid, adaptable solutions for modern warfare, ensuring compatibility with a range of aircraft platforms.
Awarded in September 2023, the SiAW contract is valued at approximately $705 million. Over the next 36 months, Northrop Grumman will focus on weapon development, platform integration, and completing a comprehensive flight test programme to support rapid prototyping and deployment by 2026.
The weapon builds on Northrop Grumman’s expertise from previous projects, including the Navy’s Advanced Anti-Radiation Guided Missile-Extended Range (AARGM-ER) and integration work on the F-35 aircraft. Work is being conducted at the company’s Northridge, California facility and the Allegany Ballistics Laboratory in West Virginia.
Susan Bruce, vice president of advanced weapons at Northrop Grumman, highlighted the programme’s innovative approach: “Northrop Grumman’s SiAW delivers on the Air Force’s desire for its first digital weapons acquisition and development program. With our expert digital engineering capabilities, this next-generation missile represents an adaptable, affordable way for the Department of Defense to buy and modernize weapons.”
The SiAW programme emphasises digital engineering and agile software development, aligning with the Air Force’s vision for modern weapon systems. By enabling rapid, lethal engagement of threats in contested environments, the SiAW enhances the Air Force’s operational capabilities and supports its shift to next-generation air power.
